  5. Sample and design total number of players tested: 665 total number of observations: 1086

  6. Morphological Physiological Technical SOCCER TALENT Psychological Sociological

  7. Height and weight • 10 skinfolds • Breadth measurements • Circumferences • Skeletal maturation (TW2) • Secundary sexual characteristics (Tanner stages)

  8. Morphological Physiological Technical SOCCER TALENT Psychological Sociological

  9. EUROFIT • Aërobic endurance • treadmill • Anaërobic endurance and power • Shuttle tempo • Van de Walle test • Speed (and agility) • 30 m sprint • 5x10 m Shuttle sprint • Strength • VTJ, CMJ • Isokinetic en isometric (BIODEX)

  10. Morphological Physiological Technical SOCCER TALENT Psychological Sociological

  11. Slalom dribbling test • Accuracy of shooting • Accuracy of passing (lob) • Juggling • Competition level: national, provincial, local • Field position

  12. Morphological Physiological Technical SOCCER TALENT Psychological Sociological

  13. Sport Interpersonal Relationship Q (Wylleman et al., 2000) • Task and Ego Oriëntation in Sport S (Duda, 1989) • Intrinsic Motivation Inventory (McAuley et al., 1989) • Self Description Q II (Marsh, 1990) • Sources of Sport-Confidence Q (Vealey et al., 1998)

  14. Perceptual skills and decision making

  15. I. Problem of maturation? • Do soccer players grow earlier and faster? • Soccer players: early or late mature? • Physical characteristics in relation to PHV?

  16. Morphological maturation: PHV • Do soccer players grow earlier and faster? average mature late mature early mature

  17. example: Height cm/year age

  18. example: Height cm/year mean age at peak velocity age

  19. Height and weight height weight APHV = 13.8 years

  20. Question 1: Do soccer players grow earlier and faster than their peers? Answer 1: earlier: probably faster: NO !

  21. 2. Soccer players: early or late mature? CL=12.0 jaar SL=9.0 jaar Height=143.1 cm CL=12.6 jaar SL=13.5 jaar Height=165.0 cm

  22. 10.5 jaar 17.5 jaar

  23. National level ?

  24. Provincial level ?

  25. Local level ?

  26. Question 2: Soccer players: early or late mature? Answer 2: on average early mature

  27. 3. Physical characteristics in relation to PHV?

  28. example: Standing Broad Jump cm/year age

  29. example: Standing Broad Jump cm/year mean age at peak velocity age

  30. Explosive strength SBJ VTJ

  31. Speed SHR SSPRINT 30m SPRINT

  32. STEMPO ESHR Aërobic and anaërobic endurance

  33. Flexibility SAR

  34. 3. Physical characteristics in relation to PHV? Strength and Speed Flexibility Aërobic and anaërobic endurance

  35. II. Talent identification: multidisciplinary Development Selection Detection Identification

  36. Aërobic endurance

  37. Aërobic endurance: VO2max

  38. Anaërobic endurance: Shuttle Tempo

  39. Speed

  40. Speed

  41. Strength

  42. Flexibility

  43. Slalom dribble

  44. Anthropometry

  45. Example: Duarte, age -16

  46. The effects of task constraints on visual search behaviour and decision-making skill in youth soccer players Roel Vaeyens, Matthieu Lenoir, Mark Williams, Liesbeth Mazyn & Renaat Philippaerts (Journal of Sport and Exercise Psychology, 2005, submitted)

  47. Test tactical skills • Universal: • film clips of simulated soccer actions • lab: projection on life-size screen • Decision taking: open offensive situations • 2 vs 1 • 3 vs 1 • 3 vs 2 • 4 vs 3 • 5 vs 3
